To all whom it may concern:

Be it known that I, LAURENCE J. BERKE- LEY, a citizen of the UnitedStates residing in the county of Milwaukee a fu clear, concise, andexact description', reference 4being had to the accompanying drawings,'forming a part of this specification.

My invention relates to systems for supplying compressed Huid, and morespecifically to a unitary compressing and storing equipment, especiallysuitable for service in connection with stations supplying free air forblowing up or iniiating automobile tires, stone cutting establishments,boiler works, in short, wherever` simplicity, compaetness, anddurability, are material 'factors in the service to be rendered by thedevice.

A complete unit for delivering compressed Huid, necessarily comprises aprime mover, a compressor, a storage receptacle, and the necessarycontrol devices for governing the operations of the prime mover and com`pressor. Where two or. more separately mounted base plates are requiredto support dilerent parts of the complete equipment, the services of acompetent construction engineer are necessary to instal 4the units.Especially, injunits of moderate capacity,

the expense of installation thus becomes an abnormally large portion ofthe 'total -exnse of the unit to the user, and'A in case 1t is desiredto move the equipment,this additional expense must be incurred aAsecondtime.

I eliminate the disadvantages hereinabove set forth, by uniting allpartsof the apparatus into a single unitary device, of such compactness andsimplicity, that any 'one with suicient intelligence to stand` the unitright end up and shelter it from the weather can secure satisfactoryservice therefrom.

Further detailed obJects and advantageous lfeatures of construction ofmy'device'wwill become apparent as the description pro-Al ceeds.

In the Vaccompanying drawings: f v Figures- 1 and 2 are elevations of a'devic constructed according to my invention looking at the side and atthe end of the unit respectively. 1

l Figlure 3 is a section on line 3-3 of Figure an 4 I y Y Figure 4 is aplan view of the base, with the storage receptacle removed.

In the embodiment of my invention selected for illustration, thetank`l0` ienetions, not only as a receptacle for the compressed iuid,but as a column 4upon which all the other arts of the com lete equipmentare supporte A base -or pe estal 12 is bolted to the bottom of the tank10 as at 14, the

bolt passing through a central boss supported` by ribs 16. A peripheralpocket 18 v formed by a ledge 20 receives the lower end of tank 10 andcoo crates :with bolt 14 to hold the parts toget er.l

A laterally pro'ecting shelf 22, forming an integral part o1base12'carries upwardly projectinv lugs 24 to which a platform 26 1spivoted carrying the prime 'mover 28 lwhich is illustrated as anelectric motor.

Another shelf 30 has integrally formed dithe periphery of tank 10, andis clamped to the tank by a U-bolt 34 passing through suitable aperturedbosses 36 at the ends of arms 32. Three vertical brace' rods 38 extendfrom lbase 12 up through shelf 30 to cooperate with .the clam ing U-bolt34 and unite the shelf base, an tank into a rigid unitary structure.

An air compressor indicated as awliole by the reference character 40 andhaving an air intake 42 and a fly wheel 44 is mounted on shelf 30.- Abelt 46 passes around ily wheel 44 and the ulle carried by theelectric'motor 28. t wi l be ap arent that the weight of` motor 28 andatform or Ashelf 26 operates to automatically maintain -pin of motor28,`and for this purpose, the

lea lines delivering electrical power to the motor extend from lthegovernor downward thereto, being housed in a protecting pipe .vergingarms 32 each embracing part ot 56. The outlet for the air is Vthroughthe pressure regulating and control valve 50 which permits the pressureof the air to be set at a predeterminedvalue lower than the pressure inthe tank 10. By turning the handle of the control valve to one controlposition, the reducing valve is by-passed and by throwing the handle toa third position, the air may be delivered to a special outlet, such asa tire filling hose as disclosed and claimed in the co-pendingapplication of Burton S. Aikman, Serial No. 498,566, filed August 19,1921. The unit herein shown is adapted to be employed for a farm pumpingsystem of the faucet controlled pneumatic displacement type. Movement ofthe control handle to either abnormal position at once functions tooperate the governor to start the compressor.

It will be seen that I have provided a selfcontained unitary device,which only needs to be stood right end up 'and connected to a source ofelectrical power and an air hose, to be in sha e for immediate service.

Without rther elaboration, the foregoing will so fully explain the gistof my invention, that others may, by applying current knowledge, readilyadapt the same for use under various conditions of service, withouteliminating certain features which may properly be said to constitutethe essential items of novelty involved, which items are intended to bedefined and Secured to me by the following claims.

I claim:

1. In combination, an elongated storage receptacle supported on end, abase for supporting the receptacle and-having means of connectiontherewith, a horizontal support havin mounting means embracing thereceptac e spaced above the bottom thereof, a pump mounted on saidsupport for filling said receptacle anda prime mover mounted on thebasebeneath the-support for driving the pump. Y l

2. In combination, a storage receptacle, a pump .associated therewith, abase for supporting the receptacle'on end, and having a boss in thebottom thereof, means for Securing the receptacle to the base throughthe medium of the boss, and a support outstanding from the receptacleand having arms and securing means embracing the.

same, the said support carrying the said pump.

3. A mounting of the comprising a base adapted to support a tank orreservoir on end, with a portion projecting beyond the tank, said basehav-` ing a flange adapted to embrace the outer surface of the tank andproviding ay peri heral pocket to receive the lower end of t e tank aboss centrally connecting the boa-,0m ont@ ank to the base, a shelfma- Yzontallysupported in spaced relation above character described the baseand connected thereto, said shelf having means to embrace the tank and apump for filling the said tank mounted on the said shelf. i'

4.
